Biology and Management of the Dutch Elm Disease Vector, Hylurgopinus Rufipes Eichhoff (Coleoptera: Curculionidae) in Manitoba By
Biology and Management of the Dutch Elm Disease Vector, Hylurgopinus rufipes Eichhoff (Coleoptera: Curculionidae) in Manitoba by Sunday Oghiakhe A thesis submitted to the Faculty of Graduate Studies of The University of Manitoba in partial fulfilment of the requirements of the degree of Doctor of Philosophy Department of Entomology University of Manitoba Winnipeg Copyright © 2014 Sunday Oghiakhe Abstract Hylurgopinus rufipes, the native elm bark beetle (NEBB), is the major vector of Dutch elm disease (DED) in Manitoba. Dissections of American elms (Ulmus americana), in the same year as DED symptoms appeared in them, showed that NEBB constructed brood galleries in which a generation completed development, and adult NEBB carrying DED spores would probably leave the newly-symptomatic trees. Rapid removal of freshly diseased trees, completed by mid-August, will prevent spore-bearing NEBB emergence, and is recommended. The relationship between presence of NEBB in stained branch sections and the total number of NEEB per tree could be the basis for methods to prioritize trees for rapid removal. Numbers and densities of overwintering NEBB in elm trees decreased with increasing height, with >70% of the population overwintering above ground doing so in the basal 15 cm. Substantial numbers of NEBB overwinter below the soil surface, and could be unaffected by basal spraying. Mark-recapture studies showed that frequency of spore bearing by overwintering beetles averaged 45% for the wild population and 2% for marked NEBB released from disease-free logs. Most NEBB overwintered close to their emergence site, but some traveled ≥4.8 km before wintering. Studies comparing efficacy of insecticides showed that chlorpyrifos gave 100% control of overwintering NEBB for two years as did bifenthrin: however, permethrin and carbaryl provided transient efficacy. -

Some species routinely attack the trunks and major limbs of their host trees, other bark beetle species mine the twigs of their hosts, pruning and weakening trees and facilitating the attack of other tree pests. While many devastating species of bark beetles are associated with New Mexico conifers, other species favor broadleaf trees and can be equally damaging.

Ecosphere 9(10):e02463. 10.1002/ecs2.2463 Abstract. In forest ecosystems, disturbances that cause tree mortality create canopy gaps, increase growth of understory vegetation, and alter the abiotic environment. These impacts may have interacting effects on populations of ground-dwelling invertebrates that regulate ecological processes such as decom- position and nutrient cycling. A manipulative experiment was designed to decouple effects of simultane- ous disturbances to the forest canopy and ground-level vegetation to understand their individual and combined impacts on ground-dwelling invertebrate communities. We quantified invertebrate abundance, richness, diversity, and community composition via pitfall traps in response to a factorial combination of two disturbance treatments: canopy gap formation via girdling and understory vegetation removal. For- mation of gaps was the primary driver of changes in invertebrate community structure, increasing activity- abundance and taxonomic richness, while understory removal had smaller effects. -
Dutch Elm Disease Pathogen Transmission by the Banded Elm Bark Beetle Scolytus Schevyrewi
For. Path. 43 (2013) 232–237 doi: 10.1111/efp.12023 © 2013 Blackwell Verlag GmbH Dutch elm disease pathogen transmission by the banded elm bark beetle Scolytus schevyrewi By W. R. Jacobi1,3, R. D. Koski1 and J. F. Negron2 1Department of Bioagricultural Sciences and Pest Management, Colorado State University, Fort Collins, CO 80523, USA; 2U.S.D.A. Forest Service, Rocky Mountain Forest Research Station, Fort Collins, CO USA; 3E-mail: [email protected] (for correspondence) Summary Dutch Elm Disease (DED) is a vascular wilt disease of Ulmus species (elms) incited in North America primarily by the exotic fungus Ophios- toma novo-ulmi. The pathogen is transmitted via root grafts and elm bark beetle vectors, including the native North American elm bark beetle, Hylurgopinus rufipes and the exotic smaller European elm bark beetle, Scolytus multistriatus. The banded elm bark beetle, Scolytus schevyrewi, is an exotic Asian bark beetle that is now apparently the dominant elm bark beetle in the Rocky Mountain region of the USA. It is not known if S. schevyrewi will have an equivalent vector competence or if management recommendations need to be updated. Thus the study objectives were to: (i) determine the type and size of wounds made by adult S. schevyrewi on branches of Ulmus americana and (ii) determine if adult S. schevyrewi can transfer the pathogen to American elms during maturation feeding. To determine the DED vectoring capability of S. schevyrewi, newly emerged adults were infested with spores of Ophiostoma novo-ulmi and then placed with either in-vivo or in-vitro branches of American elm trees. -

Gillette Museum of Arthropod Diversity, Department of Bioagricultural Sciences and Pest Management Colorado State University, Fort Collins, CO 80523 Abstract A list of 1531 species ofLepidoptera is presented, collected over 15 years (1988 to 2002), in eleven southern West Virginia counties. A variety of collecting methods was used, including netting, light attracting, light trapping and pheromone trapping. The specimens were identified by the currently available pictorial sources and determination keys. Many were also sent to specialists for confirmation or identification. The majority of the data was from Kanawha County, reflecting the area of more intensive sampling effort by the senior author. This imbalance of data between Kanawha County and other counties should even out with further sampling of the area. Key Words: Appalachian Mountains, -

Shropshire Entomology – April 2011 (No.3) A bi-annual newsletter focussing upon the study of insects and other invertebrates in the county of Shropshire (V.C. 40) April 2010 (Vol. 3) Editor: Pete Boardman [email protected] ~ Welcome ~ Welcome to the 3rd edition of the Shropshire Entomology newsletter. By the time you receive this the recording season should be under way and hopefully those cold and miserable winter days will be but a mere memory. Also underway will be the Invertebrate challenge programme of training days, a three year project funded by The Heritage Lottery Fund and The Esmée Fairbairn Foundation, which will be running around 100 events in total concentrating on the identification of some of Shropshire’s most under-recorded and under-studied invertebrates. It will also enable Shropshire Entomology to continue for the next three years, as well as enable my involvement with the SEDN as manager of the invertebrate database. Many thanks once more to everyone who has contributed to this edition. It can only function as a ‘newsletter’ if people contribute articles of news and views, so please do consider submitting articles that relate to entomology in Shropshire or entomology in general. The deadline for submission of content for Vol. 4 is Friday 16th September 2011. Please feel free to pass this newsletter on to anyone you feel might be interested in it. Note – past newsletters will soon be able to be downloaded as PDF’s from www.invertebrate-challenge.org.uk. ~ Contents ~ The Keeled Skimmer Orthetrum coerulescens -

Received: 9 October 2020; Accepted: 28 October 2020; Published: 30 October 2020 Simple Summary: Several wood-associated insects are inadvertently introduced every year within wood-packaging materials used in international trade. These insects can cause impressive economic and ecological damage in the invaded environment. Thus, several countries use traps baited with pheromones and plant volatiles at ports of entry and surrounding natural areas to intercept incoming exotic species soon after their arrival and thereby reduce the likelihood of their establishment. In this study, we investigated the performance of eight trap colors in attracting jewel beetles and bark and ambrosia beetles to test if the trap colors currently used in survey programs worldwide are the most efficient for trapping these potential forest pests. In addition, we tested whether trap colors can be exploited to minimize inadvertent removal of their natural enemies. -
